  AFSB: When I do a Google search on "Google", I see my post on Google Plus about Google Plus on page one. I see a few more of my Google Plus posts on page one when I do other searches.
  
  I know that Google is tailoring the searches for my benefit, or possibly Google Plus searches. I can't possibly be ranking for "Google" and other keywords.
  
  What is Google trying to tell me with this. Is this information useful for SEO?

  AFSB: I also see a few Google Plus posts that are not mine. Who sees these posts? All who are logged on to their Google account?

  promoz seo: These are personalized results on SERP. Most probably you were logged in and that is the reason Google showed you your G+ posts. You might have somehow engaged with the other people's G+ posts and that can be a reason, those are getting shown.
  Try Incognito window on Chrome or Private window on Mozilla to get all neutral results (non-personalized) from any type of searches on SERP.
